VENTILATOR FOR CARS.

Application filed June 14, 1922. Serial Noi 568,363.

To all whom it may concern:

Be it known that I, VINT'ON E. SISSON, a citizen of the United States, residing at Chicago, in the county of Cook and State of 11- linois, have invented certain new and useful Improvements in Ventilators for Cars, of which the following is a specification.

The object of my invention is to provide a ventilator for freight cars, which is of simple construction with a maximum of efficiency. A further object of my invention is -to provide an ellicient means for locking the blades.

Figure 18 is a vertical sectional View of the combined ventilator and lumber door attached to a car.

Figure 19 is an enlarged detail sectional view showing the construction'of the lower member of the ventilating frame adapted to a wooden car construction.

Figure 20 is a similar View showing the adaptation of the side member to a wooden car construction.

The reference numeral 1 designates the end plates of a car, which for the purpose of illustration are shown to be metal plates having horizontally disposed corrugations 2 pressed therein. These plates are secured to the usual commercial rolled angle bars 3 known as Z bars which extend from the end sill 4 to the eaves of the car and constitute end braces for the car. These end braces constitute hangers or supports to which I rivet, or otherwise suitably secure the ventilators, as will hereinafter be pointed out.

The frame of the ventilator is composed of four members, (see Fig. 6) the top 5, bottom 6, and sides 7 and 8. The top member 5 is provided with a depending flange 9 at its outer ed e which serves as a water shed or drip to shed the elements and, as will be hereinafter explained in connection with Figure 4, functions with the top vane or blade to form a weatherproof joint with said vane. Extending upwardly from the top member 5 is a flange 10 which is curved to match the curvature of the corrugations of the end sheets. This flange and the body of the'top member extend beyond the ends of the hood 9 as will be seen in Figures 10 and 11 and the top member is provided at its inner edge with perforated lugs 11.

The lower member or sill 12 of the ventilator frame has an outwardly inclined face which terminates at its outer edge in an upturned flange 13 against the outer face of which the lower edge of the lowermost vane contacts and overlaps, as shown in Figure 4 to provide a weatherproof joint. The sill isprovided with drift or drain openings 14 through which condensation and other moisture may readily pass to the outside of the car. The sill is also provided with perforated screen lugs 15, and with a depending flange 16 curved to fit the corrugations of the end sheets. At each end of the sill is a vertical flange 17 extending, at its base, the width of the sill and provided with a rivet opening 18 to facilitate the connection between the side and sill members.

The side members are similar in construc tion, therefore but one will be described in detail. The side bar or stile 7 is turned i11- wardly at its upper end as shown at 19 in Figures 4 and 6, under the top member 5 and riveted thereto and by turning this end under the top member I form a weather proof joint between the two members. The lower end of the side member is riveted to the end flange 17 on the outside thereof so at the ends of the vanes blowing the ele- 'ments in the car at the ends of the vanes.

It will be noticed that the stops 21 and 22 are alike their upper ends are back of the pivot of the vanes and that immediately under the pivots they are concaved thereby the better to shed moisture outwardly that may enter around the pivots. At the lower portion these stops are deflected rearwardly in adaptation to the formation of the lower edge of the vane and thence extend forwardly to the outer edge of the side member. The stop 23 at its lower end overlaps the flange 13 of the sill on the outside as,

shown in Figure 4. The side members have flanges 37 and 38 which are secured by rivets to the end braces 3.

The blades or vanes 25 are suitably pivoted in the side members 7 and 8 and are of such construction as to curvature that a maximum air passage is formed between them when they are open and as will be seen in Figure 4 when closed overlap substantially one half their width thereby making a weatherproof joint between them. The top edge of the top vane 25, when in its closed position, is housed in the hood and back of the flange 9 of the upper member 5 of the frame thereby providing a weather proof joint; while the lower edge of the lowermost vane overlaps outside the flange 13 of the sill member of the frame thereby making a weatherproof joint at this point.

The vane operating link 26 is secured to the vanes by means of the supports 27.

A cross brace 28 is secured between the side members of the frame and has its upper face inclined toward the outer edge of the frame to readily shed moisture. The ventilating frame is provided at its inner edge with a screen 29 to prevent the entrance of small animals when the vanes are open, also to prevent theunauthorized extraction of goods from the car. This screen is secured to the lugs 15 and 11 of the top and bottom members and similar lugs on the side membersand cross brace 28, as shown in Figure 4.

The side member 8 is provided with a vertical slot .30, the top of which, as will be seen in Figure 4, is slightly below the plane of the underface of the middle vane. A lug 31 having a substantially right angle base 32 is formed on the outer side face of the side member 8 said base 32 being perforated while a gravity lock 32 is pivotally secured at 33 to the lug 31 and provided with a lock end 34 slightly offset, vertically, from the lock 32, as shown in Figure 5 and adapted to enter the slot 30; the inner face of the lower portion of the lock end 34 being slightly bevelled to adapt it to the outer face of the vanes.

This locking member is provided with a sidewise extension 35 having a perforation and a lock pin 36 is adapted to pass through the perforations 'of'the extensions 31 and 35 thereby locking the vanes in open and closed positions. The lock pin is provided with an opening near its lower end to receive a suitable lock. hen the vanes are in closed position the lock end 34 rests against the outer face of the middle vane, and when the vanes are in open position the lock end engages the under face of the middle vane,

whereby the vanes are locked in either position. Thepin 36 is secured against loss by means of the chain 37.

In Figures 19 and 20 I have shown a slight variation in someof the details adapting the ventilator frame to a wooden car the outside wood sheathing being designated by the reference numeral 38 and the inside sheathing by 39.

In Figures 7 and 18 I have illustrated a combined ventilator and lumber door and in this embodiment of my invention the top and side members 40 and 41 and the stops 42 are substantially like similar parts heretofore described except that the stops 42 are continuous and are so formed that they provide trunnion bearings 43 for the trunnions of the vanes 44. The stops are continued as at 45 to form a bearing for the side edges of the lumber door 46 which-is journalled at its top edge in the bearing 47, also formed in the stops. The sill 6 has no flange at its front edge as in the construction heretofore described, inasmuch as a weather proof joint is formed between the lower edge of the door and the sill by means of a stiffening flange 48 formed on the lower edge of the door which fits'under the sill as shown in Figure 18. A gravity bolt 49 is slidably mounted on the lnner face of the lumber door and engages a keeper 50 on the sill to lock it in closed position while the vanes may be locked as described in connection with the other figures. A vane stop 51 is secured to' the side members of the ventilating frame. r.

Referring to. Figures 4 and 4 it will be observed that the stops at a point substantially opposite the lower edge of each vane has a flattened portion 52, which provides a substantial seat or contact for an edge portion of the flat central portion 53 of the vanes, thereby forming another weather proof joint.

It will be noted that the ventilator is supported by and between the ,end braces whereby said ventilator is protected and materially strengthened by the said end braces, besides which the end braces serve to fend off side drafts, 'and rain and snow carried bysuch drafts, from .the ventilator, as will be understood from an observation of Figure 3, from which it will be seen that side drafts will be caught under the outwardly projecting flange of the braces 3 and fended off.

The edges of the corrugated end sheets are flat in that portion which underlies the bottom flange of the end braces 3 so as to ensure a snug weatherproof joint at this point, and further to provide a flat surface upon which the flanges 37 and 38 of the side members of the ventilator maybe secured,

- as shown in Figure 3.

The stop 51 prevents the unauthorized liftin or removal of the vanes.

Re erring to Figure 6 it will be seen that the journal bearings 54 in the side members of the frame are each provided with a hood 55 in the bottom of which is a drift opening 56 to permit cinders. dust,'and elements to-escape from these hearings.

The opening 57 in the side member of the frame in Figure 18 is adapted to receive a pin or other suitable device whereby the lumberdoor may be held in open position during loading.

The lower edge of the lowermost vane in Figure l8is, when the vanes are in closed position in contact with the lumber door 46 wherebythe door is securely locked in closed position by means of said vane in addition to the gravity latch 49.

The vanes of a car ventilator are subjectedto shocks and strains incident to the shifting of the load in the car, and also the weaving of the car in'service conditions, therefore, I prefer to make the vanes corrugated, or substantially in a compound curve in cross section, whereby they may have a maximum of strength to resist these shocks and .strains.

The vanes are provided with flanges 58 on their longitudinal edges which flanges function to stiffen the vanes, and also function as baflles to prevent cinders and the elements passing into the car. In the event of a heavy rain fall accompanied by 'a high wind rain would be driven between the vanes into the car, but with vanes having baffles 58, the rain strikes the curved face of the vane and is thereby deflected outwardly, and it will fall outside of the car. The baflle 58 will deflect outwardly and downwardly any rain that may seek to pass over the upper edges of the vane. The lower edges of the vanes are also provided with stiffening ribs or flanges 59.

From the foregoing it will be seen that I have provided a ventilator which is easily assembled, strong in construction and efficient in action; also that the ventilator is one which may be quickly and easily operated and so assembled that .the blades may not be removed or the contents of the car removed by access through-the ventilator.

It is also to be understood that the embodiments of the ventilator shown are of a preferred form, but many slight changes might be made in the construction or the details of construction, without in any way departing from the spirit and scope of the invention.
